If you get a CEL with the Wideband its because your ECU is still reading the 02 sensor you have your Wideband in.

After I put my Wideband in , I got a CEL contacted my tuner (1turbofocus) Tom on here from Focus Power and he sent me a fix to disable the CEL and no more Cel for me . :)

So you didnt drill a new hole in the pipe you just replaced the correct one?

See thats what i was wondering, if i put in the wideband with the car stock and remove one of the stock o2 sensors to put in the wideband sensor if it would cause the ECU to keep the car from starting. If it just throws a CEL for a few days i can live with that.

My last car had an o2 sensor go bad and the engine died while i was driving it and wouldnt start tiill it was replaced thats why i was wondering. I had to have it towed to the shop and stuff it sucked.

a bad o2 will not cause the car to not start it may run like crap though but it will run.

when u add the wideband usually u put it where the rear on goes and then get a tune or mil eliminator to get rid of the CEL. but the rear o2 has nothing to do with car performance its just there to make sure the cat is doing its job

ok cool, the last car was a 90 dodge daytona. When the 02 went bad it stalled completly. If these cars dont do it thats good. I wasnt sure if removing it and running it with it out would cause issues till i add the tune.
